Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to an adjustable elevator shaft operating platform. Background Art

[0002] During the construction of elevator shafts in high-rise buildings, scaffolding is usually set up in the elevator shaft, and the scaffolding is used to install the steel bars and formwork support of the elevator shaft. However, at present, most elevator shaft formworks are mostly constructed by setting up a large number of steel pipe frames from bottom to top, which is not only time-consuming and labor-intensive, but also needs to be disassembled after use, which is also very troublesome. In addition, the platform for frame construction is not strong enough, which will cause certain safety hazards.

[0003] Chinese utility model patent CN202021301994.8 discloses a standardized elevator shaft support platform. Although this integrated support platform does not require the erection of a steel pipe frame, it only needs to clamp the entire frame in the elevator shaft. However, the clamping of this support platform is mainly achieved through the contact between the support frame at the bottom of the device and the floor slab, and the contact between the support platform on the opposite side of the support frame and the inner wall of the elevator shaft. Therefore, this fixing method has high requirements on the lateral dimensions of the device. When the lateral dimension differs too much from the width of the elevator shaft, there will be a risk of loose clamping, resulting in the risk of the device falling. Utility Model Content

[0004] The purpose of the utility model is to provide an adjustable elevator shaft working platform to solve the problems raised by the above-mentioned background technology.

[0005] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0006] Furthermore, a clamping seat is fixedly provided at the lower part of the push rod, and a circular clamping plate is fixedly provided at the connection between the adjusting screw and the push rod, and the outer diameter of the clamping plate is larger than the outer diameter of the adjusting screw. The clamping plate is rotatably connected to the inside of the clamping seat, and a limiting plate is fixedly connected to the clamping seat, and a clamping groove is provided on the limiting plate, and the width of the clamping groove matches the outer diameter of the adjusting screw.

[0007] By arranging a holder and a limit plate, and arranging a clamping plate at the end of the adjusting screw, the adjusting screw and the push rod are firmly connected, and the plug plate can be pushed out or pulled back from the slot through the adjusting screw, which is convenient for fixing or disassembling the entire device.

[0008] Furthermore, a groove is provided on the top surface of the slot, and a convex portion matching the groove in the slot is provided on the plug board.

[0009] By arranging a groove in the slot, the top surface of the slot is made concave-convex, thereby improving the strength of the support and thus the load-bearing performance. The convex part on the plug board cooperates with the groove to guide the movement of the plug board, making it convenient to adjust the plug board.

[0010] Furthermore, the side surface of the vertical frame facing the floor slab is flush with the side wall of the supporting platform.

[0011] The side wall of the vertical frame is flush with the side wall of the supporting platform. When the device is fixed in the elevator shaft, the vertical frame can be in close contact with the floor slab to increase the stability of the device fixation.

[0012] Furthermore, a hand wheel is fixedly connected to the adjusting screw.

[0013] Turning the adjusting screw by the hand wheel saves effort and is convenient to operate.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model provides an adjustable plug plate, and when fixing the working platform, the plug plate can be pushed out by adjusting the screw rod, so that the width of the platform matches the width of the elevator shaft, thereby ensuring that the working platform is firmly clamped.
